Pros
Pay is usually the best compared to majority of companies. Sometimes, even overtime is paid (as straight time) for exempt employees! Benefits are pretty good too (in paper): such as 4-10 work weeks, separate sick days (which Gulfstream calls PTO, and is separate from vacation), 6% match for 401k, etc. Having a Chick-fil-a and cafeteria in the main campus is good. Aircraft launch events and family day are pretty elaborate.
Cons
Both sales and upper management set very unrealistic deadlines for engineers, thus creating a lot of stress, potential for errors and eliminating the benefits such as Friday offs. Employees (even new ones) are asked by middle and lower management, who get pressure from upper management, to work around 55 hours/week (which is still not enough for the deadlines presented). While Gulfstream is on a massive hiring drive to solve this issue, this could also mean massive layoffs once the brunt of the work is done: this has happened before. Micromanagement seems to be inevitable as a result of aggressive deadlines. The promise of good work-life balance is slowly fading away.
